Here is a description of the experiment I’m working on:
Each trial begins with a center stimulus on the screen. After pressing the space bar, a peripheral stimulus appears on the screen in a varied location. Trial types include a gap condition, where the center stimulus disappears; and an overlap condition, where the center stimulus remains on the screen.
The problem I am having, is that while I can create separate trials and events for each different center stimulus, I cannot do that for the peripheral stimulus while still making it random. When I try to use stimulus lists, it won’t just choose one stimulus, and move on to the next trial–it insists on using every stimulus on the list in sequential order.
I have attached the experiment, if it helps.
